Determination of neutering status in the bitch and dog

Contributor(s): Autumn P Davidson

Introduction

  • To evaluate the need for neutering when the sterilization status of animal is unknown.
  • Also useful in the evaluation of ovarian remnant syndrome Ovarian remnant syndrome and cryptorchidism Testicle: cryptorchidism.
  • To reduce undesired and unintentional breeding Mesalliance.
  • Physical findings are only reliable when two scrotal testes are found or when obvious signs of estrus are present.
  • The amount of vaginal bleeding during proestrus and estrus in a bitch partially ovariohysterectomized is dependent on the amount of uterine tissue left behind, and can be misleadingly scant.
  • Behavioral signs can suggest the presence of a gonad in the dog (aggression, urine marking, interest in estrual bitches) and prompt further evaluation.
  • Cryptorchidism is inherited and common in many breeds. Monorchism is extremely rare.
